Montreal, July 30, 2015 – Geomega Resources Inc. (“GéoMégA” or the “Company”) (TSX.V: GMA) announces that, further to its news release of June 17, 2015, it has filed its National Instrument 43-101 technical report titled “Montviel Rare Earth Project Québec, Canada” dated June 15, 2015, on SEDAR at www.sedar.com. The report can also be found here.

The resource estimate was prepared by Elzéar Belzile, Eng., independent Qualified Person as per NI 43-101, of Belzile Solutions Inc. of Rouyn-Noranda, Québec. The resource estimate was based on analytical results from 89 diamond drill holes completed by GéoMégA during the period of 2010 to 2013. The drilling comprises approximately 21,746 assayed intervals with an average length of 1.45 meter.

Overall, the current resource estimate presents a significantly higher degree of confidence relative to the maiden resource estimate presented in 2011 (see press release September 29, 2011) as a result of more conservative prices used, large amount of additional drilling and the detailed metallurgical work that was completed over the past three and a half years. The updated resource estimate is based on a net smelter return (“NSR”) cut-off value of CAD$180 per tonne using some of the lowest discounted rare earth oxide price assumptions in the industry, a price of $45/kg for niobium oxide and, metal recovery assumptions as indicated in the press release dated May 20, 2015. The NSR cut-off value corresponds to the total cost of mining, processing, administrative, marketing and a contingency based on the assumption of a 2,500 tonnes per day underground mining operation.

Mineral resources are estimated and reported in compliance with NI 43-101. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
